It can be beneficial for travel managers to build data sourcing gradually so they are not overloaded by numbers.
TMCs and suppliers are good initial sources but adding data from expenses and the sharing economy can help buyers get a more comprehensive view of traveller spend. In some circumstances an outsourced partner can be useful to identify the data that matters.
In this video Torsten Kriedt, BCD Travel describes the stages of collecting data and where big data platforms can come into play.
He also reminds buyers that data can be used to help travellers and compliance as much as support strategy and policy.
This interview is part of a series that Business Travel iQ conducted at this year's Business Travel Show.
